摘　　要：目的：探讨超声乳化白内障吸除多焦点人工晶状体植入术的临床疗效和调节幅度。方法：对47例（47只眼）白内障患者行超声乳化白内障吸除多焦点人工晶状体植入术,观察并记录术眼的裸眼远视力、裸眼近视力、最佳矫正远视力、最佳矫正近视力及表观调节幅度（分别采用负镜片和主观移近法进行测量）。术后随访1-12个月,对术后1周、1个月及3个月的资料进行分析。结果：术后1周、1个月及3个月裸眼近视力≥J5者,分别为38例、40例和38例,远视力矫正后近视力≥J5者,分别为37例、37例和36例。主观移近法测量术后1周、1个月、3个月的调节幅度分别为（2.02±0.59）D、（1.91±0.53）D、（1.82±0.54）D。负镜片法测量的拟调节幅度分别为（1.92±0.61）D、（1.85±0.54）D、（1.79±0.49）D,差异均无统计学意义（P〉0.05）。远视力矫正后近视力和调节幅度之间呈正相关关系（P=0.00）。焦点深度范围曲线在0.0D和-3.0D左右各有一波峰,焦点深度范围为（＋1.5-4.0）D。结论：多焦点人工晶状体可提供良好的远、近视力,远期效果有待进一步观察。Objective：To investigate the clinical effects and ranges of accommodation of multifocal intraocular lens implantation of ultrasonic emulsification cataract resorption. Methods：Forty-seven patients （ 47 eyes ） with cataract were treated with multifocal intraocular lens implantation of ultrasonic emulsification cataract resorption. The naked far and near visual acuity,the best corrected far and near visual acuity and ranges of accommodation were measured. All patients were followed up for 1 to 12 months,the clinical data of patients were analyzed after 1 week, 1 month and 3 months of operation. Results：The naked near visual acuity of 38 cases at postoperative 1 week,40 cases at postoperative 1 month and 38 cases at postoperative 3 months were more than or equal to J5,the corrected near visual acuity of 37 cases at postoperative 1 week,37 cases at postoperative 1 month and 36 cases at postoperative 3 months were more than or equal to J5. Under push-up test and defocusing test,the ranges of accommodation after 1 week,1 month and 3 months of operation were（2.02 ±0.59）D,（1.91 ±0.53）D and（1.82 ±0.54）D,and（1.92 ±0.61）D,（1.85 ±0.54）D and（1.79 ± 0. 49）D,respectively,the differences of whose were not statistically significant（P〉0. 05）. The near visual acuity after correcting far visual acuity was positive correlation with the range of accommodation. Two wave crests were found at 0. 0D and -3. 0D of the curve of focus depth,the depth of focus extension was（ ＋1. 5 to 4. 0）D. Conclusions：Multifocal intraocular lens can provide good near and far visual acuity,the long-term effects of which remains to be seen.
